> they can't just shell anyone they want especially if the target is a third party that has done nothing wrong. The reality is not that clear. A lot of what governs what these agencies can and can't do comes from executive branch policies. There is a lot of gray around what is "legal" and congress likes it that way because it keeps responsibility for allowing to much or not enough surveillance far away from them. What's more, you cannot adjudicate what you don't know about and a lot of the secrecy in programs like this is just as much about keeping away civil libertarian attorneys as it is about confounding "the enemy". There's a reason the FISA court rules nearly 100% of the time with the state. Responding attorneys are rarely involved and when they are they are often hamstrung due to a lack of knowledge that prevents them from filing any kind of useful motion or raising serious opposition.
